FRANK S. BARES, OF LOUIS, MISSOURI.

JTURNAL-EBEARENG SUPPGRT.

Specification of Letters Patent.

.Patented May lfll), 1921.'

Application nled July 28, 1919. Serial No. 313,859.

1n full, clear, and exact description, such as will enable others skilled in the art to whichV it appertainsl to make and use the same, reference being had to the accompanying drawing/sl, forming part of this specification.

y invention relates to new and useful improvements in journal bearings and supports therefor, and 'particularly the journal bearings for the axles of mining cars', the principal objects of my invention being to provide a relatively simple and eiiicient bearing which, by virtue of its construction9 can be readily applied to or removed from the axle; to provide a self-alining bearing in its support; and, further, to provide a relatively simple, strong and durable support for the journal bearing., said support being constructed of ordinary `commercial shapes reqluiring very little machine work and thererore being inexpensive of manufacture. n

WVith the foregoing and other objects 1n i view, my in'ventlon consistsin certain novel features of construction and arrangement of parts, hereinafter more fully described and claimed, and illustrated in the accompanying drawings, in which- Figure 1 is an elevational view ofa journal bearing of my improved construction and showing the same positioned in a support.

Fig. 2 is a horizontal section taken ap-v proximately on the line 2-2 of Fig. 1.

Fig. 3 is a detail section taken on the line 3-3 of Fig. l.

Fig. 4 is a section taken approximately on the line 4 4 of Fig. 2.

Figo is an elevational View, of a pair ot journal bearing supports and showing the same connected by a cross tie member.

Fig; 6 is a section taken. approximately on the line 6--6 of Fig. 5.

Referring by numerals to the accompanying drawin s, 10 designates a wheel carrying axle, t e journal portion of which is mounted for rotation in a bearing termed by a plurality of rollers 11,'the latter being retained for operative position in a cage of suitable structure and said cage and rollers y being disposed within a hollow cylindrical wardly projecting .and U-shaped members 21.

member 12. The outer` end of this cylindrical member is provided with an inwardly projecting annular iiange 13 against which the corresponding end ot the cage engages and arranged within the opposite or inner end of the cylindrical member is a removable retaining ring lll which serves tohold the roller bearing within the member 12.

ormed on the outer face of the cylindrical member 12 and at a point near its longitudinal center is an annular rib 15 having a curved outer face and formed on said member 12 near its outer end is an outl annular flange 16. Formed through this flange and communieating with the roller chamber within the member 12 is an aperture 17 which is for the purpose of permitting the introduction oflubrlcant to the roller chamber and said aperture is normally closed by a removable plug 18.

The support for the journal bearing thus constructed comprises a plate 19 that is secured 1n any suitable manner to the car vbody or underframe and secured in any suitable manner to the end portions of this plate 19 are the horizontally disposed end portions 20 of a U-shaped member 21. This last mentioned member is preferably formed of a section of commerclally rolled Tbar bent to proper shape and the space between the tJ-shaped ortlon thereof and the central portion o plate 19 receives the central portion of the cylindrical member 12, and

lwhen thus positioned, the curved outer face of rib 15 bears upon the upper face of the U-shaped portion and can rock thereupon so as to be self-alining with respect to the opposite bearing.

`When member 12 is properly positioned within the ..U-shaped supporting member,

the flange 16 occupies a position immediately adjacent to the outer edge of the outer angeof the part 21, as illustrated in Fig. 2.

ln some instances it may be found desirable to tie the member of each pair of supports together and this is done by means of transversely disposed members 22 preferably angle bars, the ends thereof being fixed in any suitable manner to the end portions of the supports comprising the plates 19 (See Figs. 5 and 6.) Y

A journal bearing and supportof my improved construction is comparatively simple, can be easily and cheaply manufactured, can be readily assembled or taken apart, is very strong and durable, and the Journal bearings are mounted in the supports so that they may rock freely in all directions, thereby enabling the members Qf the pair of bearings on each axle to aline themselves with each other.

It will be readily understood that minor changes in the size, form and construction of the various parts of my improved journal bearing support can be made and substituted for those herein shown and described, Without departing fromthe spirit of my invention, the scope of which is Set forth in the appended claimsz Vhat I claim is:

1. As a new article ofmanufacture, a

journal bearing support comprising a substantially Ushaped member, the body of which is T-shape in cross section, and a plate connecting the u per ends of the legs of said U-shaped mem er.

2. The hereindescribed journal bearing support comprising a pair of plates spaced apart, a substantially U-shaped member having the upper ends of its legs securedA to each plate, and tie bars connecting the upper ends of the legs of one U-shaped member with the upper ends of the legs o'f the other member.

In testimony whereof I hereunto aiiixmy signature this 23d day of July, 1919.
